优选的，对所述基本测试者进行三维扫描时，让所述基本测试者保持坐姿闭眼不动自然状态，使用手持式三维扫描仪快速获取所述基本测试者的脸部高精度的三维数据，在所述三维扫描仪自带的软件中将所述基本测试者的脸部点云数据转换为三角网格面数据。
优选的，所述三维软件为Solid works或Autodesk Maya。
优选的，根据所述使用者的扫描数据里的鼻子、眉骨和额头与所述医用隔离眼罩基体进行布尔运算。
优选的，所述个性化医用隔离眼罩模型保存为STL格式。
优选的，采用TPU材料与SLA光固化成型技术进行3D打印。
优选的，还包括S5，后处理组装：对所述实体个性化医用隔离眼罩进行清洗、打磨、去除不必要的支撑、后固化及消毒，在所述实体个性化医用隔离眼罩的弧度鼻支架上贴覆一层海绵垫，在所述实体个性化医用隔离眼罩两侧的后端的医用隔离眼罩系带口中穿设医用隔离眼罩系带，在所述实体个性化医用隔离眼罩的前端的镜框中镶嵌高透镜片，所述实体个性化医用隔离眼罩的医用隔离眼罩框主体的两侧均设置有若干透气孔，在所述透气孔外围的过滤棉放置支架中放置过滤棉，最后得到个性化医用隔离眼罩成品。
优选的，所述医用隔离眼罩系带为弹力带，所述弹力带的连接处设置有卡扣。
本发明相对于现有技术取得了以下技术效果：
本发明对有眼疾如结膜炎等患者、易感病毒者、一线的临床医疗工作者及相关的工作人员提供一种个性化适配高、透气性高的医用隔离眼罩，在适配性与舒适性上减轻由于长时间佩戴医用隔离眼罩导致面部产生的压迫型损害。采用增材制造的方式进行制造生产，可以在完成数据合并后进行小批量快速生产，在生产周期上降低大量的工序与成本。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有付出创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明的目的是提供一种个性化3D打印医用隔离眼罩的制备方法，以解决上述现有技术存在的问题，使医用隔离眼罩与使用者吻合度高，避免污染物进入医用隔离眼罩。
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本发明作进一步详细的说明。
如图1-图4所示：本实施例提供了一种个性化3D打印医用隔离眼罩的制备方法，包括以下步骤：
S1，医用隔离眼罩基体的建立：对基本测试者进行三维扫描，得到基本测试者的面部的正面与侧面点云数据，对得到的数据进行三维设计，得到医用隔离眼罩基体；优选的，对基本测试者进行三维扫描时，让基本测试者保持坐姿闭眼不动自然状态，使用手持式三维扫描仪快速获取基本测试者的脸部高精度的三维数据，在三维扫描仪自带的软件中将基本测试者的脸部点云数据转换为三角网格面数据；三维扫描仪能够根据实物的立体信息转换为计算机能直接处理的数字信号，其生成的点云更加均匀，因此精度更高，稳定性强；
S2，使用者面部数据的采集：对使用者进行拍照或三维扫描，得到使用者的面部的正面与侧面点云数据；
S3，个性化医用隔离眼罩模型的建立：将S1中的医用隔离眼罩基体和S2中的使用者的点云数据均导入三维软件中进行布尔运算，布尔运算包括合并、切除、相交，合并剪切出符合使用者面部的个性化医用隔离眼罩模型；优选的，三维软件为Solid works或Autodesk Maya；根据使用者的扫描数据里的关键部位(如鼻子、眉骨、额头等)与医用隔离眼罩基体进行布尔运算；个性化医用隔离眼罩模型保存为STL格式；
S4，增材制造：将个性化医用隔离眼罩模型导入3D打印机匹配的切片软件中进行三维模型切片，生成3D打印机能够识别的打印格式文件，将打印格式文件输入到3D打印机中进行个性化医用隔离眼罩模型的打印制造，具体采用TPU材料与SLA光固化成型技术进行3D打印，得到实体个性化医用隔离眼罩，在一版中可同时打印25个个性化医用隔离眼罩，极大限度的缩短打印时间，达到快速定制化生产的目的；
本实施例还包括S5，后处理组装：将3D打印的实体个性化医用隔离眼罩用机械手移到后处理区域，对实体个性化医用隔离眼罩进行清洗、打磨、去除不必要的支撑(气孔支撑的去除)、后固化及消毒，具体采用医用酒精进行消毒，在实体个性化医用隔离眼罩的弧度鼻支架5上贴覆一层海绵垫7，在实体个性化医用隔离眼罩两侧的后端的医用隔离眼罩系带口1中穿设医用隔离眼罩系带，在实体个性化医用隔离眼罩的前端的镜框中镶嵌高透镜片3，实体个性化医用隔离眼罩的医用隔离眼罩框主体4的两侧均设置有若干透气孔2，透气孔2的直径为2mm，在透气孔2外围的过滤棉放置支架6中放置过滤棉，最后得到个性化医用隔离眼罩成品，继而包装、快递。
本实施例中，医用隔离眼罩系带为弹力带，弹力带的连接处设置有卡扣，便于调节松紧度。通过设置透气孔2使个性化医用隔离眼罩在使用时能够形成气流循环，提高了医用隔离眼罩的透气性，符合个人用眼护具标准的技术要求。弧度鼻支架5与使用者面部吻合度高，提高了使用的舒适度。
本实施例通过对基本测试者进行三维扫描建立医用隔离眼罩基体模型，通过对使用者进行拍照或三维扫描得到使用者的点云数据，将医用隔离眼罩基体模型和使用者的点云数据导入三维软件中，进行布尔运算，得到符合使用者面部的个性化医用隔离眼罩模型，最后将个性化医用隔离眼罩模型导入3D打印机中进行快速打印制造，可以在完成数据合并后进行小批量快速生产，在生产周期上降低大量的工序与成本。通过3D打印技术，可以快速制造应急防护用品，解决医疗防护用品短缺的问题。本实施例对有眼疾如结膜炎等患者、易感病毒者、一线的临床医疗工作者及相关的工作人员提供一种个性化适配高、透气性高的医用隔离眼罩，在适配性与舒适性上减轻由于长时间佩戴医用隔离眼罩导致面部产生的压迫型损害。
本说明书中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想；同时，对于本领域的一般技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处。综上所述，本说明书内容不应理解为对本发明的限制。
